National Weather Service Rapid City SD

.DISCUSSION...(This Evening Through Saturday)
Issued at 249 PM MDT Sat Apr 14 2018

Upper level analysis has large trof across the central CONUS with
closed low over Kansas City. Back edge of cloud cover from the
storm system has shifting into central SD. Just a few light snow
showers remain over far south central SD, with skies mostly sunny
across western SD. At the surface, high pressure has nosed into
the western Dakotas with a warm front across eastern WY.
Temperatures at 3pm range from around 30 in south central SD, to
around 50 across northeast WY. Winds were generally out of the
north at 10 to 20 mph.

Milder air will continue to build into the region tonight through
Monday as a ridge builds across the Rockies and into the Plains.
Should see a wide range of temperatures across the area each day,
with northeast WY being the warmest. Highs on Sunday will range
from the lower 30s in south central SD, to the upper 50s across
northeast WY. Highs on Monday will range from the 40s across far
northwest and central SD to near 70 across western portions of
northeast WY.

The next system will cross the region Tuesday into early Wednesday
as a compact upper low moves relatively quickly across the Northern
Plains. Cold front will cross the area early Tuesday, with gusty
winds developing in some areas behind it on Tuesday. Showers will
likely be scattered in nature with the system and mostly in the form
of rain. However, some snow showers look possible across northeast
WY, the Black Hills, and northwest SD, late Tuesday and Tuesday
night. Another strong system digging across the western US mid to
late week could bring more significant rain and snow to parts of
the area for next Friday into the first part of the weekend.
